Question

A worker drives a 0.500 kg spike into a rail tie with a 2.50 kg sledgeham-

mer. The hammer hits the spike with a speed of 65.0 m/s. If one-third of

the hammer’s kinetic energy is converted to the internal energy of the

hammer and spike, how much does the total internal energy increase?

## Answers ( )

Total internal energy increases by 1760 JStep-by-step explanation:The kinetic energy of an object is the energy possessed by the object due to its motion.

It is calculated as

where

m is the mass of the object

v is its speed

For the hammer in this problem:

m = 2.50 kg

v = 65.0 m/s

So its kinetic energy is

Then the problem says that 1/3 of the hammer’s kinetic energy is converted into internal energy: therefore, the total internal energy increases by
